Revert "Skip building the docs in linux32 testing"
[reviewed by @ronawho]

We turned off testing of chpldoc on linux32 because our machine that runs linux32
testing had too old of a Python version. Now that the machine is updated, we can
remove this code.

Passed a full paratest with futures and ensured that the impacted directory
still runs
